+#
+AX_C_CHECK_FLAG(FLAG-TO-CHECK,[PROLOGUE],[BODY],[ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tests if the C compiler supports the flag FLAG-TO-CHECK.
+#   If successfull execute ACTION-IF-SUCCESS otherwise
+#   ACTION-IF-FAILURE. PROLOGUE and BODY are optional and should be
+#   used as in AC_LANG_PROGRAM macro.
+#
+#   This code is inspired from KDE_CHECK_COMPILER_FLAG macro. Thanks to
+#   Bogdan Drozdowski <bogdandr@op.pl> for testing and bug fixes.
